ACETYLENE-LAMP.

Specification of Letters Patent.

Patented Aug. 4, 1914:.

Application filed December 22, 1913. Serial No. 808,297.

To all whom it may concern.

Be it known that I, MEYER STEIN, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented new and useful Improvements in Acetylene-Lamps, of which the following is a specification.

My invention relates to acetylene lamps and applies more particularly to that type of lamp which is portable and adapted for the use of miners.

An object of my invention is to provide a lamp comprising an acetylene gas generator wherein carbid and water may be mixed to produce a gas, the lamp being so arranged that when the main carbid supply container becomes exhausted in its supply of carbid that a second or auxiliary carbid container may be readily thrown into commission and thereby produce light even after the main supply has been exhausted. In lamps of the above character now in use, it is necessary when the carbid in the carbid container becomes exhausted, to depend upon light from another source during the time required to refill the carbid container. In my device the auxiliary carbid container will supply gas even after the main carbid con tainer has been removed for refilling. I am aware that acetylene lamps have been made wherein an auxiliary container was incorporated and a second burner was attached thereto, which burner might be lighted after the burner connected with the main carbid container has been extinguished, but the device of my invention provides an improve ment over lamps of this character, inasmuch as 1. provide but one burner which is connected to botn supplies of carbid and from which a flame may be produced from gas generated at either source.

A further object of my invention 18 to provide the necessary space for the auxiliary carbid container without increasing the size of the lamp or diminishing the capacity of either the water compartment or maln carbid container. This object has been accomplished by utilizing the space between the reflector and the main body of the lamp, which space has hitherto been unused.

Vith the above and other objects in view. my invention comprises certain new and useful combinations and arrangement of the various elements of my device, which will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out specifically in the appended claims.

The preferred embodiment of my invention is illustrated in the accompanying drawing to which reference Will be had.

Like characters of reference refer to like or corresponding parts throughout the sevcral views, and in which,

Figure l is a vertical sectional device. ig. 2 is a front elevation of my lamp, the reflector portion being removed. F1g. 3 is a top plan view of the lamp of my invention.

Referring now more particularly to the drawings, the device of my invention consists of a cup-shaped main body portion designated by numeral 1, a stationar top being formed thereover and a recessed bottom 21 fixed therein. The upper art of the main body comprises a water c. amber 3, and the lower part provides means for atview of my taching thereto a main carbid compartment.

Numeral 2 designates the carbid container which is preferably screwed into the lower portion of the main body, the carbid container having an open top, which, when the carbid container is in place, will be positioned adjacent the bottom 21 of the water chamber 3. An auxiliary carbid container is fixed to the side of the main body 1, the wall thereof being cylindrical and flared outward, providing an enlarged opening at the front of the lamp, over which a reflector member 5 is screwed. The reflector may be of any desired shape, it being provided with threads or other suitable means by which it may be fitted into the opening in the auxiliary carbid container.

Numeral 23 designates any suitable packing with which the joint may be sealed.

On the top of the main body is a water opening and cap 6, through which water may be introduced into the water chamber 3. A hollow tube 7 passes downward from the top of the main body to a position adjacent the bottom of the main carbid container, the tube passing through openings in the top of the lamp and in the recessed bottom 21 of the water chamber 3. Tube 7 is provided with a valve 15 in the bottom thereof, and a needle rod 14, of a diameter less than the inner diameter of the tube, passes longitudinally through the tube. A threaded handle 16 on the upper end of the rod 14 provides means whereby a tapered point on the lower end of the rod may be fed upward or downward into the similarly tapered valve seat 15 at the lower end of the tube, thus controlling the extent of opening at the water outlet. Holes 8, which may be of any predetermined size, are provided at any suitable point through the walls of tube 7, in that portion of the tube which is inside of the water chamber 3. Holes 8 provide means whereby the water contained in the water chamber is fed into the tube, thus to pass downward through valve 15 into the carbid container.

An auxiliary water feed tube is designated as 10, which tube is provided with a valve 11 at the lower end, which valve opens into the auxiliary carbid container 4. A needle rod 12 and actuating handle 18 is provided in tube 10, and an opening 9 in the portion of the tube inside of the Water chamber 3 provides access for the water to the tube.

It will be seen, that, as water is introduced to the carbid in the main carbid container 2 by medium of the valve 15, acetylene gas will be generated. An opening designated as 20 is provided in the recessed bottom of Water chamber 3, and an L-shaped tube 17 is provided communicating with said opening, the upper end passing outward through the wall of the water chamber 3 into the auxiliary carbid container 4. It will thus be seen that the gas generated in the main carbid container will pass upward and out of opening 20, through tube 17, and outward into the auxiliary carbid container through outlet 19. Burner 18, which communicates with the auxiliary carbid container, will be the only means of outlet for gas thus introduced into the auxiliary carbid container, and the gas passing through the burner may be lighted. It will likewise be seen that when an auxiliary supply of carbid is carried in the auxiliary container 4, the water introduced through tube 10 into the auxiliary supply, will set up a gas in that compartment which may be lighted at burner 18, even though the carbid container 2 has been removed for the purpose of replenishing the supply of carbid therein.

From the foregoing description it will be seen that the acetylene gas lamp of my invention provides means whereby an auxiliary supply of carbid is made available in case the main supply becomes exhausted, and that said auxiliary supply of carbid may be brought into use even while the container for the main supply is removed for replenishing. It will also be understood that in my device but one main outlet for the generated gas is necessary, and that, whether gas is being used from the main or auxiliary sources, the outlet'for such gas will be through the same burner.

lVhile I have herein described the preferred embodiment of my invention I do not wish to be limited thereto, except for such limitations as the claims may import, as it is obvious that the details of construction and arrangement of the various elements may be varied in many Ways.

Having thus described my invention, what I claim is 1. A lamp comprising a body providing a water chamber, a carbid container for removable connection with said body, an auxiliary carbid container fixed to said body portion and surrounding the gas outlet from the carbid container, a reflector carried by said auxiliary carbid container, means for feeding water from the water chamber to the main carbid chamber, means for feeding water from the water chamber to the auxiliary carbid container, and a burner providing an outlet for gas generated in either of said carbid containers, substantially as described.

2. The combination with an acetylene lamp, of an auxiliary gas generator positioned between the reflector and the main body of the lamp, the outlet for gas from said auxiliary gas generator being through the same burner as for gas generated in the main lamp.

3. In an acetylene lamp, a water chamber, a main carbid container, an auxiliary carbid container having a reflector in the front wall thereof, means for feeding water from the water chamber to the main carbid container, means for feeding water from the water chamber to the auxiliary carbid container, an outlet into the auxiliary carbid container for gas generated in the main carbid container, and a burner providing an outlet for gas in said front wall of the auxiliary carbid container whereby gas generated in either the main or auxiliary carbid containers may escape, substantially as described.

MEYER STEIN.
